Changes since 1.1: +3 -3 lines
Re-tiled many experiments so as to allow valid multi-processor testing
 o single processor configurations now have multiple tiles
 o multi-processor configurations now have the same number of tiles as
   the single processor config. but distrubuted
 o all output for T,S,U,V were unchanged but the cg2d output was sensitive
   to the re-tiling for some expts. Namely:
    adjustment.128x64x1, exp4, exp5 front_relax, natl_box and plume_on_slope
